Php two-dimensional array loop program code

In php, arrays are divided into one-dimensional arrays and multi-dimensional arrays. if we want to loop two-dimensional arrays, we can directly use foreach and for to traverse them. below I will introduce several two-dimensional array loops.

In php, arrays are divided into one-dimensional arrays and multi-dimensional arrays. if we want to loop through two-dimensional arrays, we can directly use foreach and for traversal, next I will introduce you to the implementation of several two-dimensional array loops. if you need to know about them, please refer.

For loops traverse two-dimensional arrays,The code is as follows:

1. Print_r ($ order_data_info );
2. Array
3. (
4. [0] => stdClass Object ([countOrder] => 3 [amntTotal] => 2380.00 [name] => test version)
5. [1] => stdClass Object ([countOrder] => 1 [amntTotal] => 2380.00 [name] => VIP Edition)
6. [2] => stdClass Object ([countOrder] => 2 [amntTotal] => 4760.00 [name] => Personal Edition)
7. )
8.  
9. $ Order_length = sizeof ($ order_data_info );
10. For ($ I = 0; $ I <$ order_length; ++ $ I)
11. {
12. $ Order_data_info [$ I]-> amntTotal = money ($ order_data_info [$ I]-> amntTotal );
13. }
14. Print_r ($ order_data_info );
15. Array
16. (
17. [0] => Array ([countOrder] => 3 [amntTotal] => 2380.00 [name] => test version)
18. [1] => Array ([countOrder] => 1 [amntTotal] => 2380.00 [name] => VIP Edition)
19. [2] => Array ([countOrder] => 2 [amntTotal] => 4760.00 [name] => Personal Edition)
20. )
21. $ Order_length = sizeof ($ order_data_info );
22. For ($ I = 0; $ I <$ order_length; ++ $ I)
23. {
24. $ Order_data_info [$ I] ['amnttotal'] = money ($ order_data_info [$ I] ['amnttotal']);
25. }

The foreach statement is used to traverse the array cyclically. each time a loop is executed, the value of the current array element is assigned to the value variable (the array pointer is moved one by one). The code is as follows:

1. Foreach ($ array as $ key)
2. {
3. If (xxxx)
4. {
5. Break; // The break terminates the loop.
6. }
7. If (zzz)
8. {
9. Continue; // continue terminates this loop and enters the next loop at the moment;
10. }
11. }
